The least violent bucking I've experienced thus far. Can anybody point me in the right direction with this issue?
Tried to capture in a log but it's not as repeatable as it has been, so my tuner saw nothing amiss. A friend looked at 2k in neutral with Torque Pro, said I'm running lean. Has anyone else experienced this bucking? If so, what did you do?

Who tuned the car? What's on it? Need a log.
